Weed trimmer extension system

ABSTRACT

A weed trimmer extension system for cutting and collecting, or dispersing weeds includes a cutting enclosure, to which can be attached a collecting bag or a cutting disperser; a replacement cutting implement; and enclosure fasteners, for attaching the weed trimmer extension system to a weed trimmer. The cutting implement can further include a cutting blade; a cutting string with a greater cutting radius so the cutting string can operate close to an obstruction, without the cutting blade causing damage to the obstruction; and a perpendicular fin, which pushes air in a circular direction of motion, thereby creating a vortex of air, which rotates in the plane spanned out by the rotating cutting blade. The cutting enclosure covers the replacement cutting implement, which propels the cuttings, contained and directed by the cutting enclosure, into either the collecting bag or the cutting disperser, which disperses the weed cuttings.

FIELD OF THE INVENTION

The present invention relates generally to the field of weed trimmingdevices, and more specifically to weed trimming devices that can collector spread weed cuttings during use.

BACKGROUND OF THE INVENTION

A weed trimmer, often also referred to as a string trimmer, weed eater,weed whip, weed cutter, or edge trimmer, works on the principle that aline is stretched out from its fast rotating head by centrifugal force,and can thereby cut grass, weed, and thin branches. A weed trimmer canalso use a chain trimmer, metal trimmer blade, or other lightweightcutting implements. Weed trimmers are characterized by having a cuttingimplement at the end of a long shaft with a handle or handles. They aredesigned as relatively lightweight devices for one-hand or two-handoperation, and sometimes can be used in conjunction with a shoulderstrap.

Weed trimmers have become very popular since their invention in theearly 1970's. However, it has remained a problem that these devices willshed the cutting remains in the immediate area of operation.

Some attempts have been made to implement container devices for the weedcuttings. Most notably, it has been attempted to combine a weed trimmerwith a weed vacuum, so that the trimmings will be collected in the weedvacuum bag. These devices suffer from a number of problems, particularlythey can become very heavy, and they are ineffective because the weedtrimmer operation does not work well in conjunction with the inwardsuction from the vacuum, causing a tendency for a proportion of thecuttings to be pushed to the side instead of into the vacuum bag.Because of these problems, such devices with container bags have notbeen adopted widely in the market place.

As such, it may be appreciated that there continues to be a need fornovel and improved weed trimming devices that can collect weed cuttingsduring use.

SUMMARY OF THE INVENTION

The foregoing needs are met, to a great extent, by the presentinvention, wherein in aspects of this invention, enhancements areprovided to the existing models of weed trimmers.

In various aspects of the invention, a conventional weed trimmer can beextended with a component that collects or disperses weed cuttingsduring use.

In an aspect of this invention, a weed trimmer extension system forcutting and collecting, or dispersing weeds can include a cuttingenclosure, to which can be attached a collecting bag or a cuttingdisperser. The weed trimmer extension system can be attached to aconventional weed trimmer.

In a related aspect of this invention, a weed trimmer with collectingbag can include a conventional weed trimmer, a cutting enclosure, towhich can be attached either a collecting bag or a cutting disperser, sothat weeds are driven from the cutting string or device, directed by thecutting enclosure into the cutting bag.

In a related aspect, a cutting implement of the weed trimmer can includea cutting blade and at least one cutting string, so that the cuttingstring is configured to have a greater perimeter reach, whereby thecutting string can cut grass or weeds close to an obstruction, such as atree or fence, without the cutting blade touching and potentiallycausing serious damage to the obstruction.

In a further related aspect, the cutting string can be mounted to theouter end of the cutting blade.

In a related aspect, the cutting enclosure can be configured with a rimthat is mounted on the inside of the upper part of the cuttingenclosure; and the cutting implement can be configured with at least onevertical fin, that is mounted perpendicular to the direction ofrotation, on an inner side of the cutting implement, between the cuttingimplement and the cutting enclosure; whereby the vertical fin willcreate a vortex of air that gets sucked in from underneath the cuttingenclosure, and is ejected out via an opening in the rim.

In an aspect, a cutting implement of a weed trimmer extension system canbe comprised of a cutting blade, which further comprises cutting edges,which face in the direction of circular rotation, and perpendicularfins, which are perpendicularly connected to the cutting blade. Theperpendicular fins push air in the direction of motion when the cuttingimplement is rotating, thereby creating a circulating planar vortex ofair inside the sidewalls of the cutting enclosure.

In a related aspect, the perpendicular fins can further includeapertures, such as holes or cutouts, which may reduce airflow andprovide space for rotation of the cutting implement.

There has thus been outlined, rather broadly, certain embodiments of theinvention in order that the detailed description thereof herein may bebetter understood, and in order that the present contribution to the artmay be better appreciated. There are, of course, additional embodimentsof the invention that will be described below and which will form thesubject matter of the claims appended hereto.

FIG. 20 shows a bottom perspective view of the naked trimmer head 110,further showing a cutting enclosure washer 812 prior to installation onthe trimmer head 110.

In the following, we describe the structure of a weed trimmer extensionsystem 100 with reference to FIG. 1, in such manner that like referencenumerals refer to like components throughout; a convention that we shallemploy for the remainder of this specification.

In an embodiment, as shown in FIG. 1, a weed trimmer extension system100, which can also be referred to as a weed trimmer extension device100, for cutting and collecting weeds can include:

-   -   a) a cutting enclosure 102;    -   b) enclosure fasteners 810, shown in FIG. 8, which can be        fastening bolts 810;    -   c) a replacement cutting implement 312, as shown in FIG. 3;    -   d) a cutting implement fastener 816, shown in FIG. 8, which can        be a cutting implement nut 816; and    -   e) a collecting bag 104;    -   wherein the cutting enclosure is attached to a naked trimmer        head 110 of a conventional weed trimmer 1700 with the enclosure        fasteners 810, and the replacement cutting implement 312 is        attached to a rotatable axle 1902 of the naked trimmer head 110,        such that the cutting enclosure 102 is configured to cover the        rotatable replacement cutting implement 312, above and to the        sides of the rotatable replacement cutting implement 312, such        that a bottom aperture of the cutting enclosure exposes the        underside of the cutting implement 312, such that the cutting        enclosure 102 in combination with a rotation of the replacement        cutting implement 312 is configured to create a substantially        planar air vortex that propels cuttings, which are contained and        directed by the cutting enclosure 102, and wherein the cuttings        are ejected through an ejection aperture in a side of a rear end        of the cutting enclosure 102.

In a related embodiment, the ejection aperture can be substantially atlevel with the plane of rotation of the replacement cutting implement312.

In related embodiments, common fastening components are bolts and othertypes of fasteners that are well known as fastening components to attacha cutting implement to an axle on common weed trimmers. FIG. 8 shows anexample of common fastening components, including enclosure fasteners,comprising fastening bolts 810, and a cutting enclosure washer 812, forattaching the cutting enclosure 102 to the standard cutting head of theconventional weed trimmer. Also shown are a separator disc 814, forseparating the cutting implement from the top 204 of the cuttingenclosure 102, and a cutting implement nut 816, for tightening thecutting implement 312, 512 to the rotatable axle 1902 of the trimmerhead 110 of the conventional weed trimmer 1700.

In a related embodiment, as shown in FIG. 2, the cutting enclosure 102can further include an ejection canal 203 for ejecting the cuttings fromthe cutting enclosure 102.

In a related embodiment, as shown in FIGS. 2 and 3, the cuttingenclosure 102, can include:

-   -   a) a sidewall 202, which covers/enclosed the cutting implement        312 to the sides of the cutting implement 312; and    -   b) a top 204, such that the top is connected with the sidewall        202, which covers/encloses the cutting implement 312 above the        cutting implement 312;    -   whereby the cutting enclosure 102 is configured to cover the        cutting implement 312, above and to the sides of the cutting        implement 312.

In a related embodiment, the cutting enclosure, as shown in FIGS. 2 and3, can have a substantially flat top 204.

In a related embodiment, the substantially flat top 204 can as shownhave a slight upward angle from an upper edge of the sidewall to acentral aperture of the top 204, where the central aperture fits with atrimmer head for connection to the trimmer head.

In a related embodiment, the slight upward angle can be substantiallyuniform in a range of 0 to 30 degrees.

In a related embodiment, a height difference between the upper edge ofthe sidewall 202 to the central aperture of the top 204 can be in arange of 0 to 5 centimeter.

In a related embodiment, the collection bag 104 can include one or moremesh screens 205, which can be made of a mesh fabric that will allowairflow, so that air pressure can be reduced when air enters thecollection bag 104 from the ejection canal 203 during operation. Themesh screen 205 thereby can function to avoid or reduce pressureaccumulation in the collection bag 104, which could decrease cuttingeffectiveness, and the mesh screen 205 can also allow a user to visuallyinspect the contents of cuttings in the collection bag 104. As shown inFIG. 2, the collection bag 104 can for example include mesh screens 205on both the top and sides.

In a related embodiment, FIG. 3 shows an underside view of the cuttingenclosure 102. The cutting implement 312 can either be a standardcutting implement, which is a part of the conventional weed trimmer1700, or can be a replacement cutting implement that is a part of theweed trimmer extension system 100. The cutting implement 312 can rotateclockwise, when viewed from below, such that the cutting enclosure 102in combination with a rotation of the cutting implement 312 isconfigured to create a substantially planar air vortex, which drivescuttings through the ejection canal through an ejection aperture 402, asshown on FIG. 4, whereby the cuttings are ejected out of the cuttingenclosure into the connecting collecting bag 104.

In a related embodiment, shown in FIG. 3, the cutting implement 312 canbe mounted with a protruding spacer 314, which protrudes underneath thecutting implement 312, whereby the protruding spacer 314 reduces a riskof close contact with the ground, thereby reducing the strength of theair vortex, to limit the risk of stones being picked up, and also reducethe risk of the cutting implement 312 impacting the ground during use.

Related to this, it may be noted that since the ground can have avarying shape and may have protrusions, such as stones, on its surface,the protruding spacer 314, may not eliminate the risk of close contactwith at least parts of the ground, since for example a stone to the sideof the protruding spacer 314, could still protrude up to hit the cuttingimplement 312. However, in general, particularly on relatively smoothground surfaces, the protruding spacer 314 can serve to reduce the riskof close contact with the ground.

In a related embodiment, the protruding spacer 314 can have a smoothlower end surface, such that when the protruding spacer 314 is rotatingwith the cutting implement 312 during use, the protruding spacer 314causes minimal friction or vibration if the protruding spacer 314impacts with ground.

FIG. 11 illustrates a side view of the cutting enclosure 102 and theejection canal 203, showing the protruding spacer 314 protrudingunderneath the enclosure, thereby preventing the bottom 1102 of thecutting enclosure from coming in contact with ground, and ensuring anopening between ground and the cutting enclosure. An external protrusion1120 of the protruding spacer 314 is defined as the vertical distancefrom the lowest edge 1122 of the bottom 1102 of the enclosure 102 to thelowest part 1124 of the protruding spacer 314. In typicalconfigurations, the external protrusion of the protruding spacer 314 canbe in a range of 0.5-2 inches. FIG. 11 illustrates a protruding spacer314 with a lower surface comprised of circular flat edge with a centeraperture, similar to the protruding spacer 314 shown in FIGS. 3, 5, and8.

FIG. 12 illustrates a side of a protruding spacer 314, wherein theprotruding spacer 314 is configured as a domed cap nut, such that thelower part is dome shaped, whereby a surface area of the protrudingspacer 314 potentially touching ground is minimized, thereby causingless friction. The domed cap nut can have a threaded cavity on the innerside, such that it can be attached to the threaded axle 1902 of thetrimmer head of a conventional weed trimmer. The lowest part 1204 of theprotruding spacer 314 is at the center point of the downward pointingdome shape.

As shown in both FIGS. 12 and 13, the protruding spacer 314 can have asmooth lower/outer end surface.

In a related embodiment, FIG. 4 shows a rear view of the cuttingenclosure, further including an end plate 410, which connects to thecollecting bag 104, and further including the ejection aperture 402, atthe end of the ejection canal 203.

In a related embodiment, the end plate 410 can further include notches412, 414 in both top corners, or other fastening mechanisms, forattaching the collecting bag 104 to the end plate 410 of the cuttingenclosure 102.

In a related embodiment, as illustrated in FIG. 2, the collection bag104 can include a bag fastener 206 for securing the collection bag tothe shaft of the conventional weed trimmer 1700. The bag fastener 206can include:

In a related embodiment, illustrated in FIG. 5, the cutting implement512 can be further comprised of a cutting blade 502, and one or morecutting strings 504, wherein the cutting string 504 is configured tohave a greater cutting radius than the cutting blade 502, extending witha greater radius in its circular sweep from the rotating axle in thecenter of the cutting enclosure, whereby the cutting string can cutgrass close to an obstruction, such as a tree or fence, without thecutting blade touching and potentially causing serious damage to theobstruction.

In a further related embodiment, the cutting string 504 can be mountedto an outer end of the cutting blade 502, for example by being loopedthrough holes in a flank at the end of the cutting blade, such asillustrated in FIG. 5.

In a further related embodiment, as shown in FIGS. 5 and 6, the tip ofthe cutting strings 504 can be configured to extend beyond a segment ofthe sidewall of the cutting enclosure 102, and during rotation protrudethrough a sidewall aperture 602, in the segment of the sidewall, whichhas been straightened to fit inside the full radius of the generallycircular sidewall.

In a further related embodiment, as shown in FIGS. 5 and 7, the cuttingblade 502, can rotate inside the perimeter of a circular two thirds rim510 that is mounted on the inside of the upper part/top 204 of thecutting enclosure 102, starting from the beginning inside sidewall ofthe ejection canal, such that the rim protrudes downward from the top204, substantially perpendicular to the top. The cutting blade 502 canfurther have mounted one or more vertical/perpendicular fins 802, asshown in FIG. 8, that are mounted perpendicular to the direction ofrotation, on the inner side of the cutting blade 502, such that the oneor more vertical/perpendicular fins 802 can be configured to rotateinside the perimeter, between the cutting blade and the upper part/top204 of the cutting enclosure, and further such that that the verticalfins 802 will strengthen the vortex of air that gets sucked in fromunderneath the cutting enclosure 102, and is ejected out via theejection canal 203.

In an alternative embodiment, illustrated in FIG. 9, a weed trimmerextension system 900 for cutting and dispersing weeds can include:

-   -   a) a cutting enclosure 102; and    -   b) a cutting disperser 904;    -   wherein the weed trimmer extension system 900 can be attached to        a conventional weed trimmer 1700 with common fastening        components, and the cutting enclosure 102 can cover a cutting        implement of the conventional weed trimmer and the cutting        implement propels cuttings, which are contained and directed by        the cutting enclosure 102, into the cutting disperser 904, which        directs and disperses the cuttings. The cutting disperser 904 is        shown mounted to disperse cuttings to an area on the left side        of the weed trimmer extension system 900, but can also be        mounted to disperse cuttings to the right side.

In an embodiment, shown in FIG. 10, a weed trimmer with collecting bag1000 for cutting and collecting weeds can include:

-   -   a) a conventional weed trimmer 110, further comprising:        -   a cutting implement 312, as shown in FIG. 3;    -   b) a cutting enclosure 102; to which can be mounted either:    -   c) a collecting bag 104;        -   wherein the cutting enclosure 102 fits over and covers the            cutting implement 312, and the cutting implement 312 propels            cuttings, which are contained and directed by the cutting            enclosure 102, into the collecting bag 104, or    -   d) a cutting disperser 904, as shown in FIG. 9.

In related embodiments, the cutting enclosure 102 can be made of aplastic material, or metal, including suitable alloys, each respectivelyof a suitable thickness and strength, well known in the manufacturing ofcommon shields for trimmer heads of conventional weed trimmers. Forexample, a gauge 13 sheet metal, such as a 3/32 inch steel plate can beused.

In a related embodiment, the collecting bag 104 can be made of a fabricor a plastic material, each respectively of a suitable flexibility,thickness, and strength. A suitable fabric material can for example be acanvas material made of cotton or linen.

In a related embodiment, as illustrated in FIG. 13, a cutting implement1300 can be comprised of:

-   -   a) a cutting blade 1302, which is a flat elongated piece,        further comprising cutting edges 1304, 1306 on the elongated        half-side of the cutting blade, which face in the direction of        circular rotation; and    -   b) perpendicular fins 1314, 1316 which are perpendicularly        connected to the cutting blade, along a length of the cutting        blade, such that surfaces of the perpendicular fins 1314, 1316        are perpendicular to the direction of motion, or velocity        vector, during rotation of the cutting implement 1300.

FIG. 14 shows a side view of the cutting implement 1300 shown in FIG.13,

In a related embodiment, as shown in FIG. 15 the perpendicular fins1314, 1316 can further comprise apertures 1524, 1526 such as cutouts orholes, which can reduce airflow, and serve to accommodate structures ofthe upper inside of a cutting enclosure, when mounted in the cuttingenclosure.

FIG. 16 illustrates a cutting implement 1300 mounted in a cuttingenclosure 102, wherein the cutting implements, as viewed from below,rotates clockwise.

In related embodiments, the perpendicular fins 1314, 1316 are configuredto push air in a circular direction of motion, thereby creating a vortexof air, which rotates in the plane spanned out by the rotating cuttingblade 1302, enclosed by sidewalls 202 and top 204 of the cuttingenclosure. The cutting blade 1302 is configured with a flat shape,whereby it creates only minimal air disturbance, and does not produceany inward or outward suction force. The cutting blade 1302 is notconfigured to function as a propeller that creates an airflow inwardstrough the plane of rotation, but rather the attached perpendicular fins1314, 1316 create a planar circulating airflow, that may radiate outwardfrom the center of rotation due to centrifugal forces, in the plane ofrotation of the cutting implement 1300, such that the cutting enclosure102 in combination with a rotation of the cutting blade 1302, creates aplanar circulating air vortex, which is then ejected via an ejectioncanal 203 through an ejection aperture 402.

In a related embodiment, as shown in FIG. 16, the cutting implement 1300can be mounted such that the perpendicular fins 1314, 1316 protrudeinwards, such that they are positioned between the cutting blade 1302and the top 204 of the enclosure 102.
